To better understand the technical solutions according to embodiments ofthe disclosure, related techniques involved in the embodiments of thedisclosure are explained below.

1. CSI Triggering State List

There are two types of CSI triggering state lists: a CSI triggeringstate list corresponding to aperiodic (AP) reporting (called aCSI-AperiodicTriggerStateList), and a CSI triggering state listcorresponding to semi-persistent (SP) reporting (called aCSI-SemiPersistentOnPUSCH-TriggerStateList).

In the definition of the CSI-AperiodicTriggerStateList, configurationinformation for each aperiodic triggering state is defined. In thedefinition of the CSI-SemiPersistentOnPUSCH-TriggerStateList,configuration information for each semi-persistent triggering state isdefined. Here, the configuration information of each triggering statemay include but is not limited to: what information to measure, whatinformation to report, a way of information reporting, etc.

2. CSI Request Field

The CSI request field is a specific information field in DCI. Acodepoint of the CSI request field is a value of the CSI request field.For example, if the CSI request field consists of two bits, a codepointof the CSI request field may be 00, 01, 10, or 11.

In an NR system, AP reporting and SP reporting may be triggered by DCI.In particular, a correspondence relation between codepoints of a CSIrequest field in the DCI and triggering states needs to be determined.That is to say, after detecting a codepoint of the CSI request field, auser equipment (UE) needs to know which triggering state the codepointcorresponds to.

3. A Relation Between Triggering States and Codepoints of the CSIRequest Field

For aperiodic reporting, all-zero codepoints correspond to no aperiodicreporting. Therefore, a starting codepoint corresponding to a triggeringstate is 1.

For semi-persistent reporting, a starting codepoint corresponding to atriggering state is 0.

In order to realize correspondence (also called mapping) betweencodepoints and triggering states, a particular mapping scheme isprovided in the embodiments of the disclosure.

FIG. 2 illustrates a first schematic flow chart of a method fordetermining a triggering state according to some embodiments of thedisclosure. As illustrated in FIG. 2, the method for determining atriggering state includes actions 201, 202 and 203.

In action 201, a terminal device receives first configurationinformation from a network device. The first configuration informationincludes configuration information of at least one triggering state.

In embodiments of the disclosure, the terminal device may be any devicecapable of communicating with a network, such as a mobile phone, atablet, a vehicle-mounted terminal device and a notebook.

In embodiments of the disclosure, the network device is a base station,for example a gNB in a 5G network, and an eNB in a 4G network.

In embodiments of the disclosure, the first configuration information istransmitted via high-level signalling. The high-level signalling isradio resource control (RRC) signalling.

In embodiments of the disclosure, the first configuration informationincludes configuration information of at least one triggering state.Further, the first configuration information may be RRC signalling forconfiguring a CSI-AperiodicTriggerStateList, or an RRC signalling forconfiguring a CSI-SemiPersistentOnPUSCH-TriggerStateList.

The first configuration information includes configuration informationof one or more triggering states. Generally, the first configurationinformation includes configuration information of multiple triggeringstates. The configuration information of each triggering state mayinclude but is not limited to: what information to measure, whatinformation to report, a way of information reporting, etc.

In action 202, the terminal device receives first control informationfrom the network device. The first control information includes a firstinformation field.

In a specific implementation, the first control information may be DCI.The first information field in the first control information may becalled a CSI request field. Further, a value of the first informationfield is a codepoint of the CSI request field. For example, the firstinformation field includes 3 bits, and a codepoint of the firstinformation field may be: 000, 001, 010, 011, 100, 101, 110, or 111.

In action 203, the terminal device determines, based on a codepoint ofthe first information field, a first triggering state identification(ID), and determines, based on the first triggering state ID, acorresponding first triggering state in the first configurationinformation; or the terminal device determines, based on the codepointof the first information field, the first triggering state at a targetposition in the first configuration information.

In embodiments of the disclosure, a codepoint of the first informationfield corresponds to a triggering state in the first configurationinformation. The correspondence relation may be determined in one of thefollowing approaches.

Approach 1: configuration information of each of the at least onetriggering state in the first configuration information includes asecond information field. The second information field indicates atriggering state ID of the triggering state.

In particular, when the first configuration information is configurationinformation for aperiodic reporting, configuration information of eachaperiodic triggering state includes the second information field. Thesecond information field indicates a triggering state ID of theaperiodic triggering state. When the first configuration information isconfiguration information for semi-persistent reporting, configurationinformation of each semi-persistent triggering state includes the secondinformation field. The second information field indicates a triggeringstate ID of the semi-consistent triggering state.

In a specific implementation, a triggering state ID (called a state ID)field (i.e., the second information field) may be added to RRCsignalling carrying the first configuration information. Theimplementation of the state ID field is described in combination withfirst configuration information for aperiodic reporting and firstconfiguration information for semi-persistent reporting respectively.

Please see table 1 in the below. Table 1 provides information of aCSI-AperiodicTriggerStateList, in which a state ID field labelled withan underline is added. It is to be noted that, in the configurationinformation of each CSI-AperiodicTriggerState, a corresponding state IDfield is added, so as to indicate the state ID corresponding to thetriggering state by the state ID field. The value of the state ID is ofa type of numeric.

Please see table 2 below. Table 2 provides information of aCSI-SemiPersistentOnPUSCH-TriggerStateList, in which a state ID fieldlabelled with an underline is added. It is to be noted that, in theconfiguration information of eachCSI-SemiPersistentOnPUSCH-TriggerState, a corresponding state ID fieldis added, so as to indicate the state ID corresponding to the triggeringstate by the state ID field. The value of the state ID is of a type ofnumeric.

By the approach 1, the terminal device can determine, based on acodepoint of the first information field, a first triggering state ID,and determine, based on the first triggering state ID, a correspondingfirst triggering state in the first configuration information.

Approach 2: a position of each of the at least one triggering state inthe first configuration information corresponds to a triggering state IDof the triggering state.

In particular, when the first configuration information is configurationinformation for aperiodic reporting, a position of each aperiodictriggering state in the first configuration information corresponds to atriggering state ID of the aperiodic triggering state. When the firstconfiguration information is configuration information forsemi-persistent reporting, a position of each semi-persistent triggeringstate in the first configuration information corresponds to a triggeringstate ID of the semi-persistent triggering state.

In an implementation, triggering state IDs of triggering states in thefirst configuration information are sorted in an ascending order from afirst position to a last position for the triggering states.

In another implementation, the triggering state IDs of the triggeringstates in the first configuration information are sorted in a descendingorder from the first position to the last position for the triggeringstates.

In a specific implementation, RRC signalling carrying firstconfiguration information may keep unchanged, and a triggering state IDis determined implicitly through a position of a triggering state. Howto determine the triggering state ID implicitly is described incombination with first configuration information for aperiodic reportingand first configuration information for semi-persistent reportingrespectively.

The first configuration information for aperiodic reporting contains alist, i.e., a CSI-AperiodicTriggerStateList, and a state IDcorresponding to a triggering state may be determined according to aposition of the triggering state in the first configuration information(i.e., the position in the RRC signalling). For example, a state IDcorresponding to a first triggering state is 0, and a state IDcorresponding to a second triggering state is 1, and so forth.Alternatively, state IDs are sorted in another order. For example, astate ID corresponding to the last triggering state is 0, and a state IDcorresponding to the last but one triggering state is 1, and so forth.

Similarly, the first configuration information for semi-persistentreporting contains a list, i.e., aCSI-SemiPersistentOnPUSCH-TriggerStateList, and a state ID correspondingto a triggering state may be determined according to a position of thetriggering state in the first configuration information (i.e., theposition in the RRC signalling). For example, a state ID correspondingto a first triggering state is 0, and a state ID corresponding to asecond triggering state is 1, and so forth. Alternatively, state IDs aresorted in another order. For example, a state ID corresponding to thelast triggering state is 0, and a state ID corresponding to the last butone triggering state is 1, and so forth.

For semi-persistent reporting, there is another implicit way ofdetermining a state ID, that is, determining a state ID according to aCSI-ReportConfigId. In particular, configuration information of eachtriggering state in first configuration information for semi-persistentreporting includes a reporting configuration identification (i.e., aCSI-ReportConfigId), and thus the CSI-ReportConfigId may be directlyused as a state ID to distinguish different triggering states.

By the approach 2, the terminal device can determine, based on acodepoint of the first information field, a first triggering state ID,and determine, based on the first triggering state ID, a correspondingfirst triggering state in the first configuration information.

Approach 3: a position of each of the at least one triggering state inthe first configuration information corresponds to a codepoint of thefirst information field.

In particular, when the first configuration information is configurationinformation for aperiodic reporting, a position of each aperiodictriggering state in the first configuration information corresponds to acodepoint of the first information field. When the first configurationinformation is configuration information for semi-persistent reporting,a position of each semi-persistent triggering state in the firstconfiguration information corresponds to a codepoint of the firstinformation field.

In an implementation, codepoints of the first information fieldcorrespond in an ascending order to triggering states from a firstposition to a last position for the triggering states in the firstconfiguration information.

In another implementation, the codepoints of the first information fieldcorrespond in a descending order to triggering states from the firstposition to the last position for the triggering states in the firstconfiguration information.

In a specific implementation, RRC signalling carrying firstconfiguration information may keep unchanged, and a triggering state isdetermined implicitly by a position of the triggering state. How todetermine the triggering state implicitly is described in combinationwith first configuration information for aperiodic reporting and firstconfiguration information for semi-persistent reporting respectively.

First configuration information for aperiodic reporting contains a list,i.e., a CSI-AperiodicTriggerStateList. A correspondence relation betweennon-zero codepoints and triggering states is determined based on theorder of positions of the triggering states in the list. For example, acodepoint ‘1’ corresponds to a triggering state at a first position, acodepoint ‘2’ corresponds to a triggering state at a second position,and so forth. Alternatively, the correspondence relation is defined in areversed order. For example, a codepoint ‘1’ corresponds to a triggeringstate at the last position, and a codepoint ‘2’ corresponds to atriggering state at the last but one position.

Similarly, first configuration information for semi-persistent reportingcontains a list, i.e., a CSI-SemiPersistentOnPUSCH-TriggerStateList. Acorrespondence relation between codepoints and triggering states isdetermined based on the order of positions of the triggering states inthe list. For example, a codepoint ‘1’ corresponds to a triggering stateat a first position, a codepoint ‘2’ corresponds to a triggering stateat a second position, and so forth. Alternatively, the correspondencerelation is defined in a reversed order. For example, a codepoint ‘1’corresponds to a triggering state at the last position, and a codepoint‘2’ corresponds to a triggering state at the last but one position.

By the approach 3, the terminal device can determine, based on acodepoint of the first information field, a first triggering state at atarget position in the first configuration information. Here, the targetposition corresponds to the codepoint of the first information field.

Approach 4: when the first configuration information is configurationinformation for semi-persistent reporting, configuration information ofeach semi-persistent triggering state in the first configurationinformation includes a reporting configuration ID, and the reportingconfiguration ID corresponds to a codepoint of the first informationfield.

In an implementation, reporting configuration IDs correspond in anascending order to codepoints of the first information field.

In another implementation, the reporting configuration IDs correspond ina descending order to the codepoints of the first information field.

In a specific implementation, RRC signalling carrying firstconfiguration information may keep unchanged, and a triggering state isdetermined implicitly by a reporting configuration ID (i.e., aCSI-ReportConfigId) corresponding to the triggering state. Inparticular, for semi-persistent reporting, each of the at least onetriggering state is configured with only one CSI-ReportConfigId (i.e.,an ID corresponding to CSI reporting configuration), and theCSI-ReportConfigId is directly used to correspond to a codepoint of theCSI request field. A correspondence relation between codepoints totriggering states is determined based on the order ofCSI-ReportConfigIds corresponding to the triggering states. For example,a codepoint ‘0’ corresponds to the minimum CSI-ReportConfigId, and acodepoint ‘1’ corresponds to the second minimum CSI-ReportConfigId.Alternatively, the correspondence relation is defined in a reversedorder. For example, a codepoint ‘0’ corresponds to the maximumCSI-ReportConfigId, and a codepoint ‘1’ corresponds to the secondmaximum CSI-ReportConfigId.

By the approach 4, the terminal device can determine, based on acodepoint of the first information field, a corresponding reportingconfiguration ID, and determine, based on the reporting configurationID, a corresponding first triggering state.

FIG. 3 illustrates a second schematic flow chart of a method fordetermining a triggering state according to some embodiments of thedisclosure. As illustrated in FIG. 3, the method for determining atriggering state includes actions 301 and 302.

In action 301, a network device sends first configuration information toa terminal device. The first configuration information includesconfiguration information of at least one triggering state.

In embodiments of the disclosure, the network device is a base station,for example a gNB in a 5G network, and an eNB in a 4G network.

In embodiments of the disclosure, the terminal device may be any devicecapable of communicating with a network, such as a mobile phone, atablet, a vehicle-mounted terminal device and a notebook.

In embodiments of the disclosure, the first configuration information istransmitted via high-level signalling. The high-level signalling is RRCsignalling.

In embodiments of the disclosure, the first configuration informationincludes configuration information of at least one triggering state.Further, the first configuration information may be RRC signalling forconfiguring a CSI-AperiodicTriggerStateList, or RRC signalling forconfiguring a CSI-SemiPersistentOnPUSCH-TriggerStateList.

The first configuration information includes configuration informationof one or more triggering states. Generally, the first configurationinformation includes configuration information of multiple triggeringstates. The configuration information of each triggering state mayinclude but is not limited to: what information to measure, whatinformation to report, a way of information reporting, etc.

In action 302, the network device sends first control information to theterminal device. The first control information includes a firstinformation field. A codepoint of the first information field is usedfor the terminal device to determine a first triggering stateidentification (ID), and to determine, based on the first triggeringstate ID, a corresponding first triggering state in the firstconfiguration information; or the codepoint of the first informationfield is used for the terminal device to determine the first triggeringstate at a target position in the first configuration information.

In a specific implementation, the first control information may be DCI.The first information field in the first control information may becalled a CSI request field. Further, a value of the first informationfield is a codepoint of the CSI request field. For example, the firstinformation field includes 3 bits, and a value of the first informationfield may be: 000, 001, 010, 011, 100, 101, 110, or 111.

In embodiments of the disclosure, a codepoint of the first informationfield corresponds to a triggering state in the first configurationinformation. The correspondence relation may be determined in one of thefollowing approaches.

Approach 1: configuration information of each of the at least onetriggering state in the first configuration information includes asecond information field. The second information field indicates atriggering state ID of the triggering state.

In particular, when the first configuration information is configurationinformation for aperiodic reporting, configuration information of eachaperiodic triggering state includes the second information field. Thesecond information field indicates a triggering state ID of theaperiodic triggering state. When the first configuration information isconfiguration information for semi-persistent reporting, configurationinformation of each semi-persistent triggering state includes the secondinformation field. The second information field indicates a triggeringstate ID of the semi-consistent triggering state.

In a specific implementation, a triggering state identification (calleda state ID) field (i.e., the second information field) may be added toan RRC signalling carrying the first configuration information. Theimplementation of the state ID field is described in combination withfirst configuration information for aperiodic reporting and firstconfiguration information for semi-persistent reporting.

Approach 2: a position of each of the at least one triggering state inthe first configuration information corresponds to a triggering state IDof the triggering state.

In particular, when the first configuration information is configurationinformation for aperiodic reporting, a position of each aperiodictriggering state in the first configuration information corresponds to atriggering state ID of the aperiodic triggering state. When the firstconfiguration information is configuration information forsemi-persistent reporting, a position of each semi-persistent triggeringstate in the first configuration information corresponds to a triggeringstate ID of the semi-persistent triggering state.

In an implementation, triggering state IDs of triggering states in thefirst configuration information are sorted in an ascending order from afirst position to a last position for the triggering states.

In another implementation, the triggering state IDs of the triggeringstates in the first configuration information are sorted in a descendingorder from the first position to the last position for the triggeringstates.

In a specific implementation, RRC signalling carrying firstconfiguration information may keep unchanged, and a triggering state IDis determined implicitly by a position of a triggering state. How todetermine the triggering state ID implicitly is described in combinationwith first configuration information for aperiodic reporting and firstconfiguration information for semi-persistent reporting respectively.

The first configuration information for aperiodic reporting contains alist, which is a CSI-AperiodicTriggerStateList, and a state IDcorresponding to a triggering state may be determined according to aposition of the triggering state in the first configuration information(i.e., the position in the RRC signalling). For example, a state IDcorresponding to a first triggering state is 0, and a state IDcorresponding to a second triggering state is 1, and so forth.Alternatively, state IDs are sorted in a reversed order. For example, astate ID corresponding to the last triggering state is 0, and a state IDcorresponding to the last but one triggering state is 1, and so forth.

Similarly, the first configuration information for semi-persistentreporting contains a list, i.e., aCSI-SemiPersistentOnPUSCH-TriggerStateList, and a state ID correspondingto a triggering state may be determined according to a position of thetriggering state in the first configuration information (i.e., theposition in the RRC signalling). For example, a state ID correspondingto a first triggering state is 0, and a state ID corresponding to asecond triggering state is 1, and so forth. Alternatively, state IDs aresorted in a reversed order. For example, a state ID corresponding to thelast triggering state is 0, and a state ID corresponding to the last butone triggering state is 1, and so forth.

For semi-persistent reporting, there is another implicit way ofdetermining a state ID, that is, determining a state ID according to aCSI-ReportConfigId. In particular, configuration information of eachtriggering state in first configuration information for semi-persistentreporting includes a reporting configuration identification (i.e., aCSI-ReportConfigId), and thus the CSI-ReportConfigId may be directlyused as a state ID to distinguish different triggering states.

Approach 3: a position of each of the at least one triggering state inthe first configuration information corresponds to a codepoint of thefirst information field.

In particular, when the first configuration information is configurationinformation for aperiodic reporting, a position of each aperiodictriggering state in the first configuration information corresponds to acodepoint of the first information field. When the first configurationinformation is configuration information for semi-persistent reporting,a position of each semi-persistent triggering state in the firstconfiguration information corresponds to a codepoint of the firstinformation field.

In an implementation, codepoints of the first information fieldcorrespond in an ascending order to triggering states from a firstposition to a last position for the triggering states in the firstconfiguration information.

In another implementation, the codepoints of the first information fieldcorrespond in a descending order to triggering states from the firstposition to the last position for the triggering states in the firstconfiguration information.

In a specific implementation, RRC signalling carrying firstconfiguration information may keep unchanged, and a triggering state isdetermined implicitly by a position of the triggering state. How todetermine the triggering state implicitly is described in combinationwith first configuration information for aperiodic reporting and firstconfiguration information for semi-persistent reporting respectively.

First configuration information for aperiodic reporting contains a list,which is a CSI-AperiodicTriggerStateList. A correspondence relationbetween non-zero codepoints and triggering states is determined based onthe order of positions of the triggering states in the list. Forexample, a codepoint ‘1’ corresponds to a triggering state at a firstposition, a codepoint ‘2’ corresponds to a triggering state at a secondposition, and so forth. Alternatively, the correspondence relation isdefined in a reversed order. For example, a codepoint ‘1’ corresponds toa triggering state at the last position, and a codepoint ‘2’ correspondsto a triggering state at the last but one position.

Similarly, first configuration information for semi-persistent reportingcontains a list, i.e., a CSI-SemiPersistentOnPUSCH-TriggerStateList. Acorrespondence relation between codepoints and triggering states isdetermined based on the order of positions of the triggering states inthe list. For example, a codepoint ‘1’ corresponds to a triggering stateat a first position, a codepoint ‘2’ corresponds to a triggering stateat a second position, and so forth. Alternatively, the correspondencerelation is defined in a reversed order. For example, a codepoint ‘1’corresponds to a triggering state at the last position, and a codepoint‘2’ corresponds to a triggering state at the last but one position.

Approach 4: when the first configuration information is configurationinformation for semi-persistent reporting, configuration information ofeach semi-persistent triggering state in the first configurationinformation includes a reporting configuration ID, and the reportingconfiguration ID corresponds to a codepoint of the first informationfield.

In an implementation, reporting configuration IDs correspond in anascending order to codepoints of the first information field.

In another implementation, the reporting configuration IDs correspond ina descending order to the codepoints of the first information field.

In a specific implementation, RRC signalling carrying firstconfiguration information may keep unchanged, and a triggering state isdetermined implicitly by a reporting configuration ID (i.e., aCSI-ReportConfigId) corresponding to the triggering state. Inparticular, for semi-persistent reporting, each of the at least onetriggering state is configured with only one CSI-ReportConfigId (i.e.,an ID corresponding to CSI reporting configuration), and theCSI-ReportConfigId directly corresponds to a codepoint of the CSIrequest field. A correspondence relation between codepoints andtriggering states is determined based on the order ofCSI-ReportConfigIds corresponding to the triggering states. For example,a codepoint ‘0’ corresponds to a minimum CSI-ReportConfigId, and acodepoint ‘1’ corresponds to a second minimum CSI-ReportConfigId.Alternatively, the correspondence relation is defined in a reversedorder. For example, a codepoint ‘0’ corresponds to a maximumCSI-ReportConfigId, and a codepoint ‘1’ corresponds to a second maximumCSI-ReportConfigId.
